Seems Turkish DAB was switched off. Digitalbitrate.com has not received it for Months.

For GSE there is an alternative to the existing pts2bbf | bbfedi2eti:

https://github.com/digris/digris-edi-zmq-bridge

This is the code for the 2 bundesmuxes on 23.5E:

1. first tune with tune-s2 with a PCIe internal card (tested with TBS 6903x), others do NOT work: tune-s2 12641 V 1500 -system DVB-S2 -lnb UNIVERSAL -modulation 8PSK -fec 2/3 -s ts -tsraw -b

2. in a second console stream it to internal port 5000: dvbstream -c 0 8192 -i 127.0.0.1 -r 5000

3. in a third console process the EDI and send it to internal port 8971: digris-edimcast2edi -m 127.0.0.1 -p 5000 -b 127.0.0.1 -G 1 -l 8971

4. in a forth console use dablin_gtk from port 8971: nc 127.0.0.1 8971 | dablin_gtk -f edi

I've tested it and it works!

Many thanks to Yoann from digris for the explanation of the correct syntax.

But for MPE you need to send the parameter -udp in dvbstream

[YoannQueret]

@andimik here an example for the MPE with the digris-edimcast2edi for the French Metropolitain 1 on 5°W, 11461H Symbol rate 5780 FEC 2/3 in QPSK/DVB-S2 with PID 301 - mcast 239.0.1.11:5001

digris-edimcast2edi -m 127.0.0.1 -p 5000 -l 8901 -F 301:239.0.1.11:5001

Please use the next branch of digris-edi-zmq-bridge

[andimik]

This is the syntax for MPE:

1. tune-s2 12168 V 27500 -system DVB-S -lnb UNIVERSAL -modulation QPSK -fec 2/3
2. dvbstream -udp -c 0 8192 -i 127.0.0.1 -r 5000
3. digris-edimcast2edi -m 127.0.0.1 -p 5000 -l 8901 -F 4121:239.128.43.43:50043
4. nc 127.0.0.1 8901 | dablin_gtk -f edi

I see that BundesMUX 1 & 2 are up again at 23.5º East 12168 V.

[andimik]

Yes, they are, but - obviously - still testing. In the last week there were lots of dropouts on 12168V, whereas the GSE signal was OK.
